The Item was the a base for a Pig Swill Dustbin to sit in. the holes in the side was to allow moisture to run out.
The bins for the waste food collection were provided by the council. They were large, heavy metal, galvanized ones, rather heavy duty dustbins, and they had heavy lids to keep out flies.
All sorts of food waste went into the buckets, from vegetable peelings to scraps of meat
The ‘pudding’ was then sold to pig farmers who added water to it to feed their pigs.
